Electrostatic discharge (ESD) is the sudden flow of electricity between two electrically charged objects caused by contact, an electrical short, or dielectric breakdown. A buildup of static electricity can be caused by tribocharging or by electrostatic induction. The ESD occurs when differently-charged objects are brought close together or when the dielectric between them breaks down, often creating a visible spark.
Nematocysts may occur scattered throughout the body surface, except the basal disc. They are abundant on the tentacles and hypostome. On tentacles they form âbattery of nematocystsâ which are used for paralyzing the prey. A battery consists of one or two large central nematocysts surrounded by 10-12 smaller ones. MECHANISM OF DISCHARGE. The discharge of nematocyst thread tube from the cnidocyte takes place due to mechanical or chemical stimuli received by the cnidocil. In a resting stage the capsule wall is not permeable to water and there is very high osmotic pressure since the hypnotoxin inside is hypertonic to external water.
